Just to let you all know, I've successfully updated to Rogero 4.21/4.25 spoofed cfw no problem. And most importantly , downgraded back to 3.55 and back up to Rogero 4.21 without a hitch, Follow what has been stated here and I don't see why it wouldn't work for you. What I did was:

I installed the Rogero CEX PS3 Custom Firmware (CFW) v4.21, and multiman was not loading so I tried to return to 3.55 with the update provided and it did return to 3.55 but now I cannot install any update of any kind, it says that the data is corrupted and it gets and error every time I try. what should I do to be able to update again?

What did you do ? You updated to Rogero 4.21 ? And run multiman , Then decided to go back to 3.55 ?
